Al-Mu'minun - 23:101

فَإِذَا نُفِخَ فِي الصُّورِ فَلَا أَنسَابَ بَيْنَهُمْ يَوْمَئِذٍ وَلَا يَتَسَاءلُونَ
[23:101]
So when the trumpet is blown, there shall be no ties of relationship between them on that day, nor shall they ask of each other.
Then when the Trumpet is blown, there will be no more relationships between them that Day, nor will one ask after another!
And when the trumpet is blown there will be no kinship among them that day, nor will they ask of one another.
